The front wall of the tray may beprovided with means for guiding said wire handle during the pullingthereof, and said latter means may also be provided with means forpermitting the free end portion of the handle to be withdrawn from thetray so that the wire may be swung backwards to allow removal of themarked invoice form from the irnprinter. It is apparent that the entireoperation may be done with the tray being held in the palm of theattendants hand. Means are also provided to lock the wire bail or handlein position when the imprinter is not in use.

Referring to FIG. 1 ofthe drawing wherein the imprinter embodying ourinvention Vis designated yby reference character 10, said imprinter isshown with the credit card 12 and the blank invoice slip 14 beinginserted in imprinting position thereon. y

The imprinter comprises a substantially rectangular tray 16 havingvertical side walls 18 and end walls 22 and 24. The base or floor 20 ofsaid tray 16 is lined with a layer 26 of a resilient material such asmolded soft rubber, and said layer 26 is provided with a group ofupstanding protrusions 28 which serve as stop members for indexing thecredit card when same is inserted into said tray. These stop membersalso provide spacing between the invoice and the layer 26 so that thecard 12 may be slipped therebetween. A slot 27 is provided in one ofsaid walls 13 and is adapted to permit ther passage of said credit `card12 into said tray 16, the card being inserted until it abuts the stopmembers 28. Embossed indicia 32 may be provided upon the layer 26 in apredetermined location adjacent the position of the embossed indiciacontained on the credit card 12. This indicia 32 may be in the form ofupraised rubber or metal type or printing blocks or the like and isgenerally utilized to convey the identifying indicia of the seller uponsaid invoice. An adjustable date stamp liner may also be utilized sothat current dates may be inserted therein.

A pair of coextensive elongate slots 34 are provided along the length ofsaid side walls 1-8, one in each said wall and said slots being parallelone to the other. Mounted in said slots at one end of said tray 16adjacent wall 22 thereof is a shaft 36, said shaft being secured inplace by washers 38 and fastening means 40 so that Said shaft is movablealong the length of ysaid slots 34 across the entire length of the tray16. Mounted for rotation uponV said shaft 36 is a roller 42. Said roller42 is formed from a non-frangible material such as soft rubber or feltor some synthetic resinwhich has been chemically treated or impregnatedwith a printing material such as ink or the like whereby when saidroller is drawn against material which has been placed over an embossedsurface, a marking corresponding to said embossedl surface Will be madeupon said material. The roller is disposed closely adjacent one sidewall of said tray so that as the shaft '36 is drawn across the tray 16,the roller comes into contact with the embossed surfaces of the creditcard 12 and other protruding indicia, through the paper of the invoiceslip 14. Wall 22 may also be provided with an outwardly extending ilange(not shown) to shield the roller 42 when the latter is rest position.

The track formed by the slots 34 forces the shaft and roller 42 to bedrawn across the length of the tray 16 so that the said roller 42 exertsa pressure against the said embossed surfaces. This is accomplished byhaving that part of the slot 34 which is designated 46 disposed parallelto but lower than portion 48 of said slot 34, the two portions beingconnected by portion 50 thereof.

It should be noted that the pressure exerted by the roller upon theinvoice surface and against said embossed sur- `faces is suiiicient toprint markings representing said indicia upon the invoice primarilybecause of the resilient nature of the lining layer 26.

The means provided for pulling the shaft 36 and roller 42 acrosssaidtray comprises a U-shaped bail 52 lhaving a looped handle 54 and ends`56 .secured around said shaft adjacent both ends thereof and on theinterior of said tray 16. The bail 52 is formed from a spring wire, theends thereof exerting a resilient force against the respective sidewalls 18 of the tray. The said -bail 52 is threaded through a pair ofspaced horizontal slots 58 and 5S formed in the front Wall 24 of saidtray so that when the looped handle 54 is pulled, the shaft 36 and itsroller 42 are forced to follow the slot or guide means 34 with pressurebeing exerted by said roller upon the invoice slip against the embossedindicia 31 and 32. Vertical slots 60 and 62 are provided in said frontwall 24 communicating with a respective one of the horizontal slots 58and 58. These latter slots 60 and 62 permit upraising of the bail 52 topermit removal of the imprinted invoice slip. The left portion of thebail 52 may be squeezed so that the arms thereof pass through the saidslots 60 and 62, and 4the iinished slip thus may be removed. Althoughshown in this embodiment as cooperating vertical and horizontal slots,an equivalent construction may -be obtained by utilizing a pair ofarcuate slots or paths formed in said front wall. Said front Wall mayalso have a midportfion 63 thereof blanked out leaving portions 65 and66. In this case slots 5S and 58 would 'be in communicay.

tion with one another, and slots 60 and 62 would be continuous with thesuch continuous slots 58 and S8', and, in actuality, would be a singlewide slot, the walls thereof being either arcuate or straight.

From the description above the operation of the novel portableimprinting device should be apparent, however, -a short descriptionthereof for illustrative purposes in connection with gasoline servicestation credit purchases may -be still in order. Initially the devicemay be readied for use by pre-insertion of a blank invoice form 16therein by squeezing the bail S2 so that it passes through slots 60 and62. The bail 52 isl then replaced through said vertical slots to liethreaded through horizontal slots 58 and 58. Thus loaded the device maybe carried in a holster (not shown) adapted to be worn upon the personof the attendant as on a belt or the like. The imprinter may just aseasily be worn unloaded, the blank invoice being placed therein at thetime of use.

When a purchase is made, the credit card identifying the purchaser ishanded to said attendant and inserted into the imprinter through theslot 27 provided therein. Then, for example, the quanitity of gasolinepurchased and the price is written upon said invoice in the spaceprovided, the bail 52 is then drawn by the .looped handle 54 so that theshaft 36 passes along the guide means track 34 with the roller 42 inpressure contact with the invoice over the embossed surfaces, theimprint being made, the bail then being pushed back -to return theroller to original condition and the credit card withdrawn.

The tray containing the thus completed invoice is then presented to thecustomer for his signature, and atte-r said signature is placed thereon,the attendant squeezes the bail 52, removes the invoice, perhaps afterchecking the signature thereon with that on the credit card forveritication of identity, and gives the credit card and a copy of theinvoice to the customer, retaining a copy for billing. The imprinter maythen be reloaded with a `fresh invoice and inserted in the holster readyfor repeated use.

The invention may conceivably need only be used for the imprintingprocess; any handwritten notations, includling the notations of amountof purchase, signature of purchaser, etc. being placed on the invoiceafter removal thereof from the imprinter device, utilizing the undersidethereof as a support.

In describing the operation of our invention, a certain order ofoperational steps were described above. It should be clearly understoodthat the order so stated is not critical and some steps can be taken outof said order, interposed with others, or even left out withoutdeparting from the scope of the invention herein described.

The invention also conceivably may comprise a tray device wherein thefloor portion 20, with its resilient layer 26 may be hinged to the rearwall 22, or even to portions of the side walls 18 closely adjacent theright hand portion of slot 34. The front and rear Walls of the tray maypossibly be eliminated altogether, with the tray floor being separatedfrom the slotted walls i8, and said removable tray having upstandingresilient clamp portions substituting for said Walls 22 and 24.

The invention also contemplates that the entire credit card may beaccommodated within the said imprinter device by increasing the widththereof. While the slot -27 maybe convenient for inserting the creditcard 12, said card may be merely placed upon the interior of the traywith the embossed area upraised, the card resting upon the resilientlayer 26, with the invoice form placed over said card.

A substantial savings in time results from the convenience in utilizingthe invention by conducting the entire transaction at the exact site ofthe transaction without leaving the customer, without returning to anymain oiiice, or other area, station, or going anywhere else to imprintsaid invoices. MoreI important is the increased customer satisfactionresulting from speedy service obtainable through the use of our novelportable imprinter.

Although We have particularly shown our portable irnrinter associatedwith use in a gasoline service station, it is obvious that our device isapplicable to any use whereupon embossed indicia 4is `desired to beimprinted upon a material and said imprinting device is `desired to becarried upon the person of the individual using same.

=It is believed that our invention, its mode of operation andconstruction and assembly, and many of its advantages should be readilyunderstood from the foregoing without further description, and it shouldalso be manifest that while a preferred embodiment of the invention hasbeen shown and described for illustrative purposes, the structuraldetails are nevertheless capable of Wide varation within the purview ofour invention as defined inthe `appended claims.
